"lhc broad idvn involrvd in my invention in to provide un ons torintorrnptiug tho inlzikr ot' gnsolvnu for tho purpose of prvvvnlzing thoflow of cnrirhod rupor through the intake pipe of u, nmnifold ot-n1iinternal i-onihustion engimi for the purpose of economiziiig in theconsumption of fuel "under Vii rious emergencies and operatingconditions i-sperially where an internal combustion is utilized fordriving 'a motor vehicle. I have therefore devised means capable ofready installation in connectionwith various'types of ca rburetingappara'tusesnccording to the construction thereof, one form of the.invention being adaptable to carburetors h vlyeafor regain; the {low ofgasolene to tha carburetor in" another form of the il'iVEIltlOIlhelp nplicable'tothe intake pipis of mahifiilii cases whiarethe carburetor-lg!nrenobfirovided types of structures, I have sho wnin Fig, 1

of a moton means whereby the inflow of gasolene into a earbureter may becontrolled. and have also shown means whereby the flow of enriched vaporthrough the intake manifold pipe may be regulated: these deviees bothaccomplishin; the same result.

The invention is shown as applied to an internal eombnstion engine .2obviously of any suitable type. the latter here being shown as mountedupon the frame of an automobile It and is provided with an intake pipe 4for the manifold 5. To the lower end of the intake pipe -i there isconnected it earbureter it a simple type'of which is shown, this beingprovided with a needle valve 7 operative to open or rinse the inlet port8 connected to the gasolene supply pipe (not shown). The needle *alve 7has an upwardly extending stem portion 9 passing through the top of thecarburetor, the stem being surrounded by a spring, 10 reacting on theearbureter or other suitabl support and against the lower side of a heador shoulder 11 on the end oi the stem 9. For the purpose oftllpiessitlgl' the needle valve against the opening aetion of its spring10 there is provided a rod or iever 12 which may. be suitably eouneetedto the head 11 in this instant-e the rod being passed through the dash1' and provided with a pedal 14 on its outer end to be disposedeonveniently to the operator o that the lever may be op erated by footif desired. it is desirable that the open position ot' the needle valve,7 may he regulated so as to give the best running elli i n y by theproper supply of lzhnlene to the earbureter and engine. and to tltll't.this proper adjustment. an adjust in; llt\'lt in the form of a serew l iis provided and adjustable in a eonvenient support or threaded hraeketarm 17, the serew having uitable r nneetion with an adjusting rod 18whieh may be extended up through the dash and provided with a handle ortreadle 19 as may be desired. Obviously the adjusting serew It? ran be.turned to any suitable position to bear against the head ll of the stem9 ol' the needle valve and the. point of the latter properly disposedtlt't'tH'tling to the eonditiou to permit the. normal in How ofgasolen'e for the formation of a rombustible vapor.

From the foregoing it. will be seen that the operator when desiring toslow down the peed of the ear or when roasting, may we tirelyrut oil thesupply of gasolene at the supply port H by the applieation ol' the foot.to the pedal ti and the losing ot' the valve 7 aL'ainst ils spring it).the valve being held (l i-t(l tor anv suitable period and then whenreleased by the operator :uiloinatii'allv opens to the position a;determined by th adjust.- int! devire lfi.

.The interruption of the supply of a roln int-dildo vapor to the motormay be aehieved a artiou ol' the spring.

also by the provision of a suitable form of valve here shown as athree-way valve 20 mounted in the intake or supply pipe 4 and having alever arm 21 to \vhieh is eonneeted a push rod 22 extended through thedash l3 and provided with a treadle or handle :23 on its inner endwithin eonvenient reaeh ol the operator. The valve 20 is adapted to benormally malintained and automati -ally re turned to open position bythe provision of any suitable device as for instanee a spring 25 one endof whieh is eonneeted to the push rod 2'2 and the other to anyconvenient fixed part as for instance to the dash 13. So long as thevalve 20 is in an open position combustible vapor is drawn by the.operation of the engine piston into the cylinder through the supply ofair and gasolene at. the earbureter; but when the valve 20 is thrown toa position to out off How from the earlnireter, it. will then openeommunieation with a port- :20 leading to the atmosphere outside of thepipe, so that on the combustion stroke of the piston in the motor. airunder atmospheric pressure may pass t'reely into the rylinders of theengine and thus obviate any undue tendency to the formation of a vacuumin the cylinder.

It, will be seen that; either form of my invention is capable ofperforming the desired funetion ot' interrupting the flow of an enriehedvapor to the manifold of the engine if desired, with the resultingmaterial saving of gasolene at the time when a eombustible vapor is notdesired in the engine.

it is understood ot' eourse. that there may he various nmdilieations ndehanges in the organization, details of parts and the rombination of thesame without departing from the spirit of my invention and within the 5limits of the appended claims.
